cation and in the drawings accompanying the same I. have desxibed 60- andshown certainpreferredr embodrntifhts I of my invention, but these embodiments'are `used merelyifor illustration, and I do' not desire to limit myself to the details thereof any more than as specified in the claims, asniy invention is capable of being. embodied in many otlertstructural forms.

\ Referring-to the drawings in detail, and particularly to 'Figs i, 2 and 3, the numeral.'

"f In y this specifi 70 ber`whici,ias shown in Fig.` 3, is trans-i versely split at the point 2. This rim-base `isprovided-at one or` both edges With inivardly inclined oreilianginglv 'or hooked flanges 3* adapted to engage with, and re?y ,tain upon the rimbase, the endless tire re-` taining ilanges 4. As will `be understood, `in :some cases one endless retaining flange `may be used, other means being provided` toreta'inuthe other side of the tire, such as a Wretaining flange formed integrally with the rimbase f The retaining flanges if are each formed on one side with a groeve 5 shaped to receive e ne of" he projecting beads of a clencher,y tire, as indicated in dotted lines in Fig. 1. The other sideofI each flange is'provided ith" a curved surface or roll 6 adapted t0. engage and support the foot ot a straightsided tire, the roll being for the purposegefoo `preventing the cutting .ofthe tireybfthe `edge 'of the flange in case the tire" becomes deflated Whilein use. It hasliereto'fore `been considered/ necessaryv to have this curvedibeaiing surface `followV the line of the foot of the tire continuously to the sur.` face of the rim base in order to properly support the tire. I have found` however, "that this is not necessary, but that if the tire is supported by the curved surface of "the rim flange near the edge thereof, the [action of the rim and tire is entirelyT satisfacto-ry. I accrrdingly form in the ange a groove? shaped to receive the overhangng or hooked flange 3, the wall 8 of the groove preferably having the same inclination as.

the inner wall ofthe flange 3, sothat it will be closelyv engaged by said flange. 'When the anges are inthe position shown in Fig. 1,`4

therefore, that is, in position `toretain a..

' clencher tire, the wallsk 8 ofthe grooves 7 engage closely against the flanges 3 and the' flanges are held firmly in position u on the rim base. The stress placed upon t e tire- `retaining flanges by an inflated clencher tire is approximately in the directionindicated,

by the arrow 9 in Fig. 1, this direction being,vas willl be seen, approximately-,normal tothei-surface 8 and 'the contacting inner surface ofthe flange ,3. There i's-thus n0 tendency for tlie tire-retaining flange to roll or tiltl over the flange 3, or for it to stretch over it by enlarging in'diameter, as the' stress ris directly toward the Ainner surface ofV theafl'ange and there is .no component parallel ,with such surface, as where a vertical side flange is used. It'will. thusbe seen that itis impossible for the tire-retainingflange Ito escape from the side flange on,

i 'the rim base -without actually shearing ofi' the latter.v 'A much stronger 'structure is what lighter.

thus produced than where a vertical side flange `is used engaging a vertical face o-n 'the tireeretaining flange. 'Atv the same time` a substantial saving in .weight is possible,

asffthe section is reduced by an amount e nale'4 tothe sectional area of the groove 7. jlei' thereon, but it is thel usual practice'to carry tween the tire supporting'slIrfaces-...Q the tire-retaining fianges when mounted in position, to support a ystraight-sided tire, this'v :distance rbeing represented by the dimension b in Fig. A2, shall :be somewhat gre'tvlter than the distance between the edges of the flanges when mounted in "position, to ,retain al clenclier' tire, as indicated by the dimension'v ain Fig.y 1-. ,The dimension b is preferably about one-tenth o J an inch greater than the 75l dimension a.- /The inturned or hooked formation of vthe'lianges 3 hi's another importantffunction. When a, transversely split rim baseer rim has lbeen used heretofore-Iil&j. has ordinarily been -found necessary to pril-,f 8p vide means for locking' the rim against. ac cidental collapse when removed from the felly. The felly will ordinarily prevent w such collapse whenv the rim is mounted l one or lmore of theserims provided with in- Iflated tires" to be substituted upon the felly in case of accident. In such case, of. course,

resultant saving in weight' of the tire-retain# ing. flanges `iswery material, and owing-to the increased strength of the improved structure, a further saving in weight'may be effected by making all of the p artssoine'- When the rim is to be used flanges removed. and replaced -in reverse position, as indicated in Fig. 2. ,When 1n this ,position the toe 10 of each tire-retaining rflange enters the space beneath the corresponding'flange 3 and seats securely therein.

The flanges 3 are preferably given just thev `\the arrow p. ,iper inward inclination toifit the toe of a tire-retaining flange provided with agroove for a clencher bead of standard dimensions The resultant stress placed upon the tireretaining flange oy a straight-sided "re is in approximately the direction -indicated`by.v`1910. I do-not wish 24 in Fig. 2, and, as wil1"be.seen, v such stress-will have a tendency to force the toe of the flange always more firmly into its scat. The outwardly curved edges or rolls 6V of the tire-retaining flangesy give the'sides of .the tire adequate support at the point where support is needed, and also provide rounded surfaces tosupport the tire if it should be necessary to use the same tcmpml rarily while deflated. Itis `also possible to so proportionthe parts that the space beto `"carry av straight-sided tire. the transversely split rim vbase is collapsed and the tii'e-retainin vthe rim, receives no .internal support and must be securely held fromy collapsing under v the pressure of the inflated tire. yWith the construction shownl such collapse is effectually, prevented by" the engagement of. the base portions "ofi the tire-retaining' V.flanges beneath the ,flanges 3. The expansion'of'the inflated rtire holds theseparts in secure engagement, and it is therefore impossible forV .theriiii-base tocolla se..Y The endless flanges also/prevent the un ueexpansion of the rim base, sof'tht no lockingmeans whatever are required for the ends of the latter.

For removably mounting the rim base upon thev wheel felly, any suitablemeans may be used,`the's`e means, however, forming no part of my resent invention. For example; the rim aseV may be provided withl inwardly or downwardly projecting flanges 11 and 12 engaging beveled vsurfaces 13 and 14 of a felly band 15 permanently mounted upon thefelly 16. The beveled surfaces'on the rim ba'seand felly band may be fored into enga ement by means of the rotata le eccentrief` eepers 17,` or by any other suite" able devices. vThe specific construction of the rotatable' keepers is not 'set fprth herein, as thesame is fully described, illustrated and claimed iii-my co-/pending application Serial Number 589,680, lfiled October 29,
